[OctDev] imread does not work on octave-3.0.2 on cygwin

From: Tatsuro MATSUOKA <tmacchant@ya...> - 2008-11-08 03:54

Hello

A inquiry for imread in image package has been carried out one of the thread of octave in
Japan

***********
im=imread('im1.bmp');

convert: unable to open image `/cygwin/tmp/oct-22d688.0.ppm': No such file
or directory.
error: imread: error running ImageMagick's 'convert'
error: evaluating if command near line 113, column 5
error: called from `imread' in file
`/home/tosiyuki/octave/image-1.0.8/imread.m'
error: evaluating assignment expression near line 1, column 5
********

I also have tried it
************
octave:12> pkg list
Package Name | Version | Installation directory
-------------------+---------+-----------------------
image *| 1.0.8 | /usr/share/octave/packages/image-1.0.8

octave:13> im=imread('test.bmp');
convert: unable to open image `/programs/cygwin/tmp/oct-22d944.3.ppm': No such file or
directory.
error: imread: error running ImageMagick's 'convert'
error: evaluating if command near line 113, column 5
error: called from `imread' in file `/usr/share/octave/pack
*************

The same error happens.

Any suggestions?

Regards

Tatsuro

Hi Tatsuro,

it is not a fault of image.

I don't know for wich reason on cygwin
the TMPDIR enviroment is set to
C:/CYGWIN/TMP instead of /TMP

see src/sysdep.cc call to
cygwin32_conv_to_full_win32_path

Probably is for old compatibility with non cygwin
programs, but it confuse cygwin programs like
convert of ImageMagick.

As workound is possible to

setenv ("TMPDIR","/tmp")
before
im=imread('im1.bmp');

I will try to remove the issue on the next
octave cygwin release.

Regards
Marco

I built a preliminary version of 3.0.3
without that issue.

http://matzeri.altervista.org/cygwin-gcc4/octave/

Could you give a test ?

Marco

MMMMMMM

I have installed 3.0.3 binaries.

$ ls -l /bin/octave.exe
lrwxrwxrwx 1 Tatsu none 16 Nov 18 18:45 /bin/octave.exe -> octave-3.0.3.exe

Tatsu@Shiro ~
$ /bin/octave

Tatsu@Shiro ~
$

octave was not be executed.

I have tried ./rebaseall but the problem did not be solved.

Regards

Tatsuro
